The Bike-sharing Blog has more details on the system, which will start out with 1,100 bikes.
"In six months this Clear Channel-operated system was planned and installed. The system is starting in four districts of the capital with plans to expand to the rest of the city with a total of 6,000 bikes. According to Cuidadanosenred, Jorge Borobia, director of Clear Channel Mexico, said that depending on the operation of this first stage, it will be analyzed, before extending the service to other areas of the city. As with other Clear Channel SmartBike systems, yearly subscription registration for a system RFID card must be bought online or at the Ecobici office."
